Here, the button B31 is anoperator for selecting the visible light communication using the backlight 1101 of the clerk display unit 110. The button B32 is an operatorfor selecting the visible light communication using the lighting device40.

In the configuration of the present embodiment, a transmission methodselected in the operation of the button B32, that is, the visible lightcommunication using the lighting device 40 requires a communication withthe server device 20, and thus cannot be realized in an environment inwhich a communication with the server device 20 is not established.Therefore, when a communication with the server device 20 is notestablished, for example, the communication unit 106 is linked down, thesetting change supporting portion 151 may perform control so that thebutton B32 is not selected by disabling or hiding the button B32.

In the transmission method selection screen G3 described above, themaintenance staff can select a desired transmission method via theoperation unit 109. The setting change supporting portion 151 transmitsthe setting content of the setting item of which the setting is changedby the transmission method selected from the transmission methodselection screen G3.

Here, the information obtained by associating the setting item to be atarget of the setting change with the setting value of the correspondingsetting item is included in the setting content transmitted from the POSterminal 10. The setting content may include the information indicatinga terminal ID (for example, the name of a machine or an IP address) thatidentifies the POS terminal 10, a file name of the setting information1053 to be a setting target, or the like.

In FIG. 8, for example, when the button B31 is selected, the settingchange supporting portion 151 transmits the changed setting content ofthe setting item from the back light 1101 by the visible lightcommunication in cooperation with the first modulation unit 153 and thefirst light source control unit 154. For example, when the button B32 isselected, the setting change supporting portion 151 transmits thesetting content of the setting item of which the setting is changed tothe server device 20, in cooperation with the transmission unit 152.Accordingly, in the server device 20, the setting content transmittedfrom the POS terminal 10 is transmitted from the lighting device 40 bythe visible light communication. That is, the setting change supportingportion 151 transmits the setting content of the setting item of whichthe setting is changed from the lighting device 40 by the visible lightcommunication in cooperation with the transmission unit 152 and theserver device 20.

The setting change supporting portion 151 causes the transmission methodselection screen G3 to display an end button B34 according to theoperation of the button B31 or the button B32. For example, in thefollowing process, when it is confirmed with the repair terminal 30 thatthe setting content is not wrong, the maintenance staff instructs an endof the setting change by operating the end button B34. When an operationof the end button B34 is received, the setting change supporting portion151 ends a setting change supporting process by eliminating atransmission method selection screen G4.

A return button B33 provided on the transmission method selection screenG3 is an operator for instructing a return to the item selection screenG1 or the setting input screen G2. When an operation of the returnbutton B33 is received, the setting change supporting portion 151eliminates the transmission method selection screen G3 and displays theitem selection screen G1 or the setting input screen G2 again. Forexample, in the following process, when a setting mistake in the settingcontent is detected with the repair terminal 30, the maintenance staffcan perform resetting such as a correction of the setting item in whicha setting mistake is detected by operating the return button B33.

Referring back to FIG. 5, the transmission unit 152 transmits thesetting content of the setting item of which the setting is changed tothe server device 20 in cooperation with the setting change supportingportion 151. The setting item transmitted to the server device 20 istransmitted by the visible light communication via the lighting device40.

The second modulation unit 252 generates the control signal fortransmitting the setting content received by the reception unit 251 bythe visible light communication. Specifically, the second modulationunit 252 generates the control signal for the visible lightcommunication by superimposing the information indicating the settingcontent received by the reception unit 251 on the control signal forcontrolling the light emission of the lighting device 40.

The second light source control unit 253 controls the light emission ofthe lighting device 40 based on the control signal generated by thesecond modulation unit 252. The second light source control unit 253transmits the setting content received by the reception unit 251, thatis, the setting content when the setting is changed with the POSterminal 10 by the visible light communication, by controlling the lightemission of the lighting device 40.

The repair terminal 30 includes a reception unit 351, a matching unit352, and an output unit 353, as the functional units.

Some or all of the functional units described above may be a softwareconfiguration which is realized in cooperation with a program stored inthe processor (for example, the CPU 301) and the memory (for example,the ROM 302 and the storage unit 305) of the repair terminal 30. Some orall of the functional units of the functional units described above maybe a hardware configuration realized by a dedicated circuit or the likemounted on the repair terminal 30.

The reception unit 351 is an example of the reception means. Thereception unit 351 receives the information transmitted by the visiblelight communication by analyzing the image data obtained by the imagingwith the imaging unit 310. Specifically, the reception unit 351 analyzesthe intensity (vibration) of the light received by the imaging unit 310to acquire the information superimposed on the corresponding light.

For example, when the clerk display unit 110 is imaged with the imagingunit 310, the reception unit 351 analyzes the intensity of light emittedby the back light 1101 that is imaged in a moving image to acquire thesetting content superimposed on the corresponding light. For example,when the lighting device 40 is imaged with the imaging unit 310, thereception unit 351 analyzes the intensity of the light emitted by thelighting device 40 that is imaged in a moving image to acquire thesetting content superimposed on the corresponding light.

The matching unit 352 is an example of the matching means. The matchingunit 352 determine whether the setting changed by the POS terminal 10 isappropriate on a per setting item basis by matching the setting contentreceived by the reception unit 351 with the matching setting information3051 stored in the storage unit 305.

Specifically, the matching unit 352 matches the setting value of thesetting item included in the setting content with the setting value ofthe corresponding setting item stored in the matching settinginformation 3051 on a per setting item basis. Also, as a result of thematching, the matching unit 352 determines that the setting item ofwhich the setting value is identical is appropriate and determines thatthe setting item of which the setting value is not identical isinappropriate.

The output unit 353 is an example of the output means. The output unit353 outputs a matching result of the matching unit 352. Specifically,the output unit 353 causes the display unit 309 to display and output ascreen presenting the determination result on a per setting item basisobtained by the matching of the matching unit 352. Hereinafter,referring to FIGS. 10 to 12, a screen example output by the output unit353 is described.

FIGS. 10 to 12 are diagrams illustrating examples of a screen displayedby the output unit 353. Referring to FIG. 10, a matching result screendisplayed when there is a setting item determined as inappropriate isdescribed.

FIG. 10 is a diagram illustrating an example of the matching resultscreen. As illustrated in FIG. 10, a matching result screen G5 has anarea A51 for displaying a matching result of the matching unit 352. Amatching result on a per setting item basis which is included in thesetting content is displayed on the area A51.

Specifically, the output unit 353 displays the setting item and thesetting value included in the setting content and the matching result(OK or NG) of the matching unit 352 in a correlating manner. Here, acase where the setting value of a setting item “IP address” is thematching result “NG” is exemplified, and the output unit 353 highlightsand displays an entry of the corresponding “IP address”. The output unit353 causes the matching result screen G5 to display a notification of asetting mistake and a message M51 promoting resetting with respect tothe setting item “IP address” of which the matching result is “NG”.

Accordingly, the maintenance staff looks at the matching result screenG5 described above and can easily confirm the appropriateness of thesetting changed by the POS terminal 10 and the setting item in which asetting mistake is detected. In this case, the maintenance staff canefficiently reset the setting item in which a setting mistake isdetected by operating the return button B33 displayed on thetransmission method selection screen G4 of FIG. 9.

The example of FIG. 10 is a form in which a setting value which isincluded in the setting content and is wrong is displayed with respectto the setting item “IP address” in which the matching result is “NG”,but the form is not limited to this, and a correct setting value storedin the matching setting information 3051 may be displayed in acomparable manner.

FIG. 11 illustrates another example of a matching result screen. Asillustrated in FIG. 11, a matching result screen G6 has an area A61 fordisplaying the matching result of the matching unit 352 in the samemanner as the matching result screen G5 of FIG. 10. Here, a displayexample when matching results are “OK” with respect to all setting itemsis illustrated.

When the matching results are “OK” with respect to all setting items,the output unit 353 displays a confirmation screen display button B61and an end button B62 as illustrated in the matching result screen G6.Here, the end button B62 is an operator for instructing an end of thesetting change. When an operation of the end button B62 is received, theoutput unit 353 eliminates the matching result screen G6 and ends anoutput process.

Meanwhile, the confirmation screen display button B61 is an operator forinstructing transition to a confirmation screen for generating evidencedata indicating performance of the setting change. When an operation ofthe confirmation screen display button B61 is received, the output unit353 eliminates the matching result screen G6 and causes the display unit309 to display the confirmation screen illustrated in FIG. 12.

FIG. 12 is a diagram illustrating an example of the confirmation screen.As illustrated in FIG. 12, an area A71 for displaying a content of thesetting changed with the POS terminal 10 is provided on a confirmationscreen G7. A set of the setting items and the setting values included inthe setting content transmitted from the POS terminal 10 is displayed inthe area A71. The present embodiment is configured to instruct a displayof the confirmation screen G7 from the matching result screen G6displayed when it is determined that all setting items are appropriate,and thus the setting items that are determined as appropriate in thematching unit 352 are displayed in the area A71.

Date information M71 indicating a current date and maintenance staffinformation M72 indicating the name or the like of the maintenance staffoperating the repair terminal 30 are displayed on the confirmationscreen G7. For example, the maintenance staff information may be set inthe storage unit 305 in advance or may be input via the operation unit308.

An area A72 for inputting a signature of a manager to approve the changework is provided on the confirmation screen G7. Here, the manager meansa shop manager of the store or a manager who manages the POS terminal 10in the store. When the operation unit 308 is configured with a touchpanel, for example, handwritten characters can be input in the area A72,and an approval signature is input by the manager.

When the operation unit 308 is not configured with a touch panel, forexample, a form in which the confirmation screen G7 is printed by usinga printer device (not illustrated) connected to the repair terminal 30so that an approval signature is entered in the area A72 may bepossible. In this case, an operator for instructing the printing of theconfirmation screen G7 may be independently provided.

An end button B71 and a return button B72 are provided on theconfirmation screen G7. Here, the end button B71 is an operator forinstructing an end of the confirmation work. When an operation of theend button B71 is received, the output unit 353 stores the confirmationscreen G7 in the storage unit 305 as the evidence data, and theneliminates the confirmation screen G7, to end an output process. Bydisabling or hiding the end button B71 until an approval signature isinput in the area A72, a control may be performed so that storage of theevidence data while an approval signature is not input is suppressed.

The return button B72 is an operator for instructing a return to thematching result screen G6. When an operation of the return button B72 isreceived, the output unit 353 eliminates the confirmation screen G7 anddisplays the matching result screen G6 again.

A device which is an output destination of the output unit 353 is notlimited to the display unit 309. For example, when a printer device isconnected to the repair terminal 30, a form in which the printer deviceis set as the output destination, and the evidence data or the like isprinted and output to the printer device may be possible.

As described above, in the repair system 1, the setting is changed bythe maintenance staff with the POS terminal 10, the setting contentchanged by the setting change is transmitted by visible lightcommunication via the clerk display unit 11 or the lighting device 40.Therefore, the maintenance staff can input the setting content of thesetting information changed with the POS terminal 10 to the repairterminal 30 by causing the imaging unit 310 of the repair terminal 30carried by the maintenance staff to face the clerk display unit 110 orthe lighting device 40.

Therefore, in the repair system 1, even in an environment in which therepair terminal 30 cannot be connected to the network N1 or the POSterminal 10, for example, because of the security or the like, thesetting content when the setting is changed with the POS terminal 10 canbe delivered to the repair terminal 30. Since the maintenance staff canacquire the setting content when the setting is changed with the POSterminal 10 without performing a procedure for connection to the POSterminal 10 or the network N1, the repair work can be efficientlyperformed.

The repair terminal 30 determines whether the setting content when thesetting is changed with the POS terminal 10 is appropriate by matchingthe setting content received by the visible light communication with thematching setting information 3051 stored in advance. The repair terminal30 outputs the determination result of the appropriateness on a persetting item basis when the setting is changed.

Accordingly, the maintenance staff can easily confirm theappropriateness of the setting changed with the POS terminal 10 via therepair terminal 30. Therefore, in the repair system 1, since theconfirmation work of the setting content visually performed by themaintenance staff can be omitted, the setting change can be efficientlyperformed and the generation of the setting mistake due to theconfirmation omission or the like can be suppressed.

An operation example of the repair system 1 described above isdescribed.

Referring to FIG. 13, first, an operation example of the POS terminal 10is described. FIG. 13 is a flowchart for describing an example of aprocess performed by the POS terminal 10. As a premise of this process,it is assumed that the POS terminal 10 is operated in a maintenancemode. In the present process, for convenience of description, processesaccording to the operations of the return buttons B22, B33, and the likeillustrated in FIGS. 7 to 9 are appropriately omitted.

First, the setting change supporting portion 151 stands by until anoperation (hereinafter, also referred to as a setting change operation)of inputting an instruction of the start of the setting change isreceived (ACT 11; No). When the setting change operation is received(ACT 11; Yes), the setting change supporting portion 151 causes theclerk display unit 110 to display an item selection screen (refer toFIG. 6) for selecting a setting item of a setting target based on thesetting information 1053 (ACT 12).

Subsequently, the setting change supporting portion 151 stands by untila setting item is selected from the item selection screen (ACT 13; No).When the selection operation of the setting item is received (ACT 13;Yes), the setting change supporting portion 151 causes the clerk displayunit 110 to display a setting input screen (refer to FIG. 7) forinputting a setting value of the selected setting item (ACT 14).

Subsequently, the setting change supporting portion 151 stands by untilthe setting value is input on the setting input screen (ACT 15; No).When the setting value is input (ACT 15; Yes), the setting changesupporting portion 151 updates the setting information 1053 byoverwriting the input setting value on the setting value of thecorresponding setting item stored in the setting information 1053 (ACT16).

Subsequently, the setting change supporting portion 151 causes the clerkdisplay unit 110 to display the transmission method selection screen(refer to FIG. 8) for selecting a transmission method of the settingcontent when the setting is changed (ACT 17). Subsequently, the settingchange supporting portion 151 stands by until the transmission method isselected (ACT 18). Specifically, the setting change supporting portion151 stands by until any one of the clerk display unit 110 (the backlight 1101) and the lighting device 40 is selected.

Here, when the lighting device 40 is selected (ACT 18; No), thetransmission unit 152 transmits the setting content set in ACT 16 to theserver device 20 (ACT 19), and transitions to ACT 23.

Meanwhile, when the clerk display unit 110 is selected (ACT 18; Yes),the first modulation unit 153 generates the control signal for thevisible light communication on which the setting content set in ACT 16is superimposed (ACT 20). Subsequently, the first light source controlunit 154 controls the light emission of the back light 1101 based on thecontrol signal generated in ACT 20 (ACT 21), transmits the settingcontent by the visible light communication using the back light 1101(ACT 22), and transitions to ACT 23.

Subsequently, the setting change supporting portion 151 causes the clerkdisplay unit 110 to display a screen (refer to FIG. 9) for notifyingthat the setting content is transmitting by the selected transmissionmethod (ACT 23). Subsequently, the setting change supporting portion 151determines whether the end operation of the setting change operation isreceived (ACT 24).

Here, due to the resetting of the setting value or the like, it isdetermined that an end operation is not performed (ACT 24; No), thesetting change supporting portion 151 returns the process to ACT 12, sothat the setting item of the setting target is selected again. When theend operation is received (ACT 24; Yes), the setting change supportingportion 151 ends the present process.

Subsequently, referring to FIG. 14, an operation example of the serverdevice 20 is described. FIG. 14 is a flowchart for describing an exampleof a process performed by the server device 20.

First, the reception unit 251 stands by until the setting content of thesetting changed with the POS terminal 10 is transmitted from the POSterminal 10 (ACT 31; No). When the reception unit 251 receives thesetting content from the POS terminal 10 (ACT 31; Yes), the processtransitions to ACT 32.

The second modulation unit 252 generates the control signal for thevisible light communication on which the setting content received in ACT31 is superimposed (ACT 32). Subsequently, the second light sourcecontrol unit 253 controls the light emission of the lighting device 40based on the control signal generated in ACT 32 (ACT 33) to transmit thework content by the visible light communication using the lightingdevice 40 (ACT 34). Also, the second light source control unit 253returns the process to ACT 31.

Subsequently, referring to FIG. 15, an operation example of the repairterminal 30 is described. FIG. 15 is a flowchart for describing anexample of a process performed by the repair terminal 30. In the presentprocess, for convenience of description, a process according to theoperation of the return button B72 or the like illustrated in FIG. 12 isappropriately omitted.

First, the reception unit 351 monitors the image data imaged with theimaging unit 310 and stands by until the setting content is transmittedby the visible light communication (ACT 41; No). When the settingcontent is received (ACT 41; Yes), the reception unit 351 transitionsthe process to ACT 42.

Subsequently, the matching unit 352 matches the setting content receivedin ACT 41 with the matching setting information 3051 stored in thestorage unit 305 and determines the appropriateness of the setting valueon a per setting item basis included in the setting content (ACT 42).

Subsequently, the output unit 353 determines whether all setting itemsincluded in the work content are determined as appropriate based on thematching result of ACT 42 (ACT 43). When a setting item determined asinappropriate is included (ACT 43; No), the output unit 353 causes thedisplay unit 309 to display a matching result screen (refer to FIG. 10)for promoting resetting together with presenting the matching result ofACT 32 (ACT 44) and returns the process to ACT 41.

Meanwhile, when all setting items are determined as appropriate (ACT 43;Yes), the output unit 353 causes the display unit 309 to display amatching result screen (refer to FIG. 11) presenting the matching resultof ACT 42 (ACT 45). Subsequently, the output unit 353 determines whetherthe display of the confirmation screen is instructed (ACT 46). Here,when the display of the confirmation screen is not instructed (ACT 46;No), the present process ends.

When the instruction of the display of the confirmation screen isreceived (ACT 46; Yes), the output unit 353 causes the display unit 309to display the confirmation screen for inputting the approval signature(ACT 47). Subsequently, the output unit 353 stands by until the approvalsignature is input on the confirmation screen (ACT 48; No).

Also, when the input of the approval signature is received (ACT 48;Yes), the output unit 353 stores the confirmation screen on which theapproval signature is input as the evidence data (ACT 49), the presentprocess ends.

As described above, in the repair system 1, when the setting is changedwith the POS terminal 10 by the maintenance staff, the setting contentwhen the setting is changed is transmitted by the visible lightcommunication via the clerk display unit 110 or the lighting device 40.In the repair system 1, when the repair terminal 30 receives the workcontent transmitted by the visible light communication, the repairterminal 30 matches the work content with the matching settinginformation 3051 and causes the repair terminal 30 to display the screenindicating the appropriateness of the setting content on a per settingitem basis.

According to the repair system 1, the maintenance staff carrying therepair terminal 30 can be notified of the appropriateness of the settingcontent when the setting is changed with the POS terminal 10.Accordingly, the repair system 1 can notify the maintenance staff of theappropriateness of the setting content when the setting is changed inreal time. Accordingly, in the repair system 1, since the generation ofa setting mistake due to the confirmation omission can be suppressedtogether with the omission of the confirmation work by the visualobservation of the maintenance staff, the change work of the settinginformation can be efficiently performed.

According to the repair system 1, by the visible light communicationusing the back light 1101 or the lighting device 40, the setting contentof the POS terminal 10 can be delivered to the repair terminal 30without connecting the repair terminal 30 to the network N1.Accordingly, even in the environment where the repair terminal 30 cannotbe connected to the network N1 or the POS terminal 10, the settingcontent when the setting is changed with the POS terminal 10 can bedelivered to the repair terminal 30. Accordingly, since the maintenancestaff can acquire the setting content when the setting is changed withthe POS terminal 10 in the repair terminal 30 by imaging the clerkdisplay unit 110 or the lighting device 40 without the procedureaccording to the communication with the POS terminal 10, the change workof the setting information or the repair work can be efficientlyperformed.

Second Embodiment

Subsequently, the second embodiment is described. According to the firstembodiment described above, a form in which the POS terminal 10 istransmitted end time to the server device 20 via the network N1 isdescribed. However, the transmission method of the end time with respectto the server device 20 is not limited to this. Here, according to thepresent embodiment, a form in which the end time is transmitted to theserver device 20 by using the visible light communication is describedas an example of another transmission method. Configurations which arethe same as those in the first embodiment are denoted by the samereference numerals, and the description thereof is omitted.

FIG. 16 is a diagram illustrating an example of the repair systemaccording to the present embodiment. As illustrated in FIG. 16, a repairsystem 2 includes the POS terminal 10, a server device 50, the repairterminal 30, and the lighting device 40. The repair system 2 furtherincludes an imaging device 60. Here, the server device 50 and thelighting device 40 are connected via the cable N2 such as a controlline. The server device 50 and the imaging device 60 are connected via acable N3 such as a data transmission line. According to the presentembodiment, the server device 50 is disconnected from the network N1.

The imaging device 60 is an imaging device having an image sensor suchas a CCD or a CMOS. For example, the imaging device 60 is a monitorcamera installed on a ceiling part of an area where the POS terminal 10is provided, and can image at least the clerk display unit 110 includedin the POS terminal 10.

According to the present embodiment, the imaging device 60 can image amoving image as the image data. The imaging device 60 is used forreceiving light emitted by the clerk display unit 110 (the back light1101) or the lighting device 40. Instead of the imaging device 60, aconfiguration in which a light receiving device for the visible lightcommunication is included may be possible.

The server device 50 is a device corresponding to the server device 20of the first embodiment described above. For example, the server device50 has a hardware configuration illustrated in FIG. 17. Here, FIG. 17 isa diagram illustrating an example of the hardware configuration of theserver device 50.

As illustrated in FIG. 17, the server device 50 includes the controlunit 200 of the computer configurations such as the CPU 201, the ROM202, and the RAM 203. The storage unit 205 and the communication unit206 are connected to the control unit 200 via the bus 204. The lightingdevice 40 and the imaging device 60 are connected to the control unit200 via the bus 204, the input and output controller 207, and the like.The image data imaged with the imaging device 60 is input to the controlunit 200.

For example, the server device 50 has a functional configurationillustrated in FIG. 18. Here, FIG. 18 is a diagram illustrating anexample of a functional configuration of the server device 50.

As illustrated in FIG. 18, the server device 50 includes a receptionunit 551, the second modulation unit 252, and the second light sourcecontrol unit 253, as the functional units.

Here, the reception unit 551 is a functional unit provided instead ofthe reception unit 251 described above. The reception unit 551 analyzesthe image data imaged with the imaging device 60 to receive theinformation transmitted by the visible light communication.Specifically, the reception unit 551 analyzes the intensity (vibration)of the light received by the imaging device 60 to receive theinformation that is superimposed on the corresponding light.

For example, the reception unit 551 analyzes the intensity of the lightemitted by the back light 1101 of the clerk display unit 110 from theimage data of the clerk display unit 110 imaged by the imaging device 60to receive the setting content superimposed on the corresponding light.That is, the POS terminal 10 and the server device 50 according to thepresent embodiment can transmit and receive the setting content by thevisible light communication.

The second modulation unit 252 performs operations which are the same asthose in the first embodiment based on the end time received by thereception unit 551. Accordingly, the server device 50 can transmit thesetting content when the setting is changed with the POS terminal 10 tothe repair terminal 30 by the visible light communication via thelighting device 40 in the same manner as the server device 20.

Subsequently, referring to the flowchart of FIG. 14 described above, anoperation example of the server device 50 is described.

First, the reception unit 551 monitors the image data imaged with theimaging unit 310 and stands by until the setting content is transmittedby the visible light communication (ACT 31; No). When the reception unit551 receives the setting content (ACT 31; Yes), the process transitionsto ACT 32. Processes subsequent to ACT 32 are the same as those in FIG.7, and thus the descriptions thereof are omitted.

As described above, according to the present embodiment, the settingcontent can be delivered from the POS terminal 10 to the server device50 by using the visible light communication. Accordingly, for example,when the POS terminal 10 is operated by standing alone or in theenvironment where the network connection with the POS terminal 10 andthe server device 20 is disconnected, the setting content when thesetting is changed with the POS terminal 10 can be delivered to theserver device 50. Accordingly, the same effect as in the embodimentdescribed above can be achieved.

When the configuration of the present embodiment is employed, thetransmission unit 152 of the POS terminal 10 becomes unnecessary, andthus may be configured to be disabled or may be removed from the POSterminal 10.

The embodiments (the first embodiment and the second embodiment)described above can be appropriately modified to be implemented bychanging a part of the configuration or function of each devicedescribed above. Therefore, some modifications according to the aboveembodiment are described below as other embodiments. In the following,points different from the above embodiment are mainly described, anddetailed description of points common to the already described contentswill be omitted. The modified examples described below may beimplemented individually or may be appropriately combined andimplemented.

(Modification 1)

In the above embodiment, the example in which the LED is used as thelight sources of the back light 1101 and the lighting device 40 is usedis described, but the type of the light source is not limited to this.Here, it is preferable to use a light source that can be modulated in ahigh frequency band where the human eyes do not feel flicker.

Further, in the above embodiment, an example in which the visible lightcommunication is performed by using the back light 1101 of the clerkdisplay unit 110 is described, but the light source device of the POSterminal 10 used in the visible light communication is not limited tothis. For example, the visible light communication may be performed byusing the back light of the customer display unit 111. For example, thevisible light communication may be performed by using an indicator lampincluded in a device such as the printer 112.

When other light source devices other than the back light 1101 and thelighting device 40 are used, a light source device to be used may beselected together with other light source devices on the transmissionmethod selection screen described above.

(Modification 2)

According to the above embodiment, a case where the setting is changedin one POS terminal 10 is described, but the same can be applied to acase where the setting change operation is performed in parallel for theplurality of POS terminals 10. In this case, each of the POS terminals10 includes the terminal ID for identifying its own POS terminal 10 inthe setting content and performs transmission.

The output unit 353 of the repair terminal 30 outputs the matchingresult of the setting content performed in the matching unit 352 on aper terminal ID basis included in the corresponding setting content.Accordingly, the appropriateness of the setting change performed in eachof the POS terminals 10 may be independently output on a per POSterminal 10 basis.

(Modification 3)

The above embodiment is a form in which the POS terminal 10 performs thevisible light communication by the lighting device 40 via the serverdevice 20, but the embodiment is not limited to this. A form in whichthe POS terminal 10 directly controls the light emission of the lightingdevice 40 may be possible. In this case, for example, the POS terminal10 and the lighting device 40 are connected to each other via a controlline, and the first modulation unit 153 and the first light sourcecontrol unit 154 perform the visible light communication by using thelighting device 40. Therefore, since the setting content when thesetting is changed by the POS terminal 10 can be delivered to the repairterminal 30 in the visible light communication by the lighting device40, the same effect as the above embodiment can be achieved.

When the configuration of the present modification is employed, thetransmission unit 152 of the POS terminal 10 becomes unnecessary, andthus may be configured to be disabled or may be removed from the POSterminal 10.

(Modification 4)

In the above embodiment, a form in which the POS terminal 10 selectivelyuses one light source device from among the light source devices of theclerk display unit 110 (the back light 1101) and the lighting device 40connected to its own device and performs the visible light communicationis described. However, the embodiment is not limited to this form, andthe POS terminal 10 may have a form of performing the visible lightcommunication by using all light source devices connected to its owndevice.

In this case, the setting change supporting portion 151 of the POSterminal 10 may display a screen for notifying that transmission isbeing performed by using the clerk display unit 110 (the back light1101) and the lighting device 40, instead of the transmission methodselection screen illustrated in FIGS. 8 and 9.

(Modification 5)

The above embodiment is described by using the POS terminal 10, but theinformation processing device to be the target of the setting change isnot limited to the POS terminal 10. For example, even when the target isthe server device 20 or an information processing device such as apersonal computer (PC) (not illustrated), the system configuration orthe device configuration which are the same as those in the aboveembodiment may be applied. Therefore, even in a setting change work of aPC used in an office, the same effect as the above embodiment can beachieved.

The program performed in each device according to the above embodimentis provided by being combined in a ROM or the like in advance. Theprogram executed in each device according to the above embodiment may beconfigured to be recorded in a computer-readable recording medium suchas CD-ROM, a flexible disk (FD), CDR, and a digital versatile disk (DVD)in a file in an installable format or in an executable format.

The program executed by each device of the above embodiment may beconfigured to be stored on a computer connected to a network such as theInternet, and may be configured to be provided by being downloaded viathe network. The program executed by each device of the aboveembodiments may be configured to be provided or distributed via anetwork such as the Internet.
